I'm not sure if it is related to the error on the plugin. I hope you can help me on this.

Thanks in advance.

It's a programming error of the plugin. "Uncaught Error: Call to undefined function vc_shortcode_custom_css_class() ..." means that one script wants to use a function that is not provided by itself or other components. Sometimes this occurs with incomplete or corrupt plugins or themes. It can also occur when one part of an installation is not compatible with the selected PHP version while another part is.
